‘It is a war of drones now’: the ever-evolving tech dominating the frontline in Ukraine

Models for reconnaissance, rescue, interception and attack are changing the way both sides operate

It's more exhausting," says Afer, a deputy commander of the Da Vinci Wolves", describing how one of the best-known battalions in Ukraine has to defend against constant Russian attacks. Where once the invaders might have tried small group assaults with armoured vehicles, now the tactic is to try and sneak through on foot one by one, evading frontline Ukrainian drones, and find somewhere to hide.

Under what little cover remains, survivors then try to gather a group of 10 or so and attack Ukrainian positions. It is costly - in the last 24 hours we killed 11," Afer says - but the assaults that previously might have happened once or twice a day are now relentless. To the Da Vinci commander it seems that the Russians are terrified of their own officers, which is why they follow near suicidal orders.
